About M-Series Connectors

There are multiple sizes of connectors which
practitioners tend to call "Microdot". The most common size
uses
10-32
threads, but there are also
5-44
and
1/4-32
variants, as shown in this image.

This style of connector was pioneered by Malco in
the late 1950's and early 1960's. Malco was later
bought by Microdot, which was later bought by Tyco.
Because of this history, users in the
industries that use this connector style still
call this a "Microdot connector", or even "Malco
Connector", even though there are now multiple
manufacturers making compatible connectors.
"Microdot" is a trademark of Tyco.

The connectors we provide are compatibles made by
various manufacturers. They are often improved
designs, mechanically more durable than the original
Malco connector.

10-32 (M) Connector Details

These connectors have threads that are the same as
those on a 10-32 (UNF) machine screw. They are
commonly used in non-destructive testing (NDT) and
aerospace, on transducers, accelerometers, strain
gauges, and force and acoustic sensors, among other
applications.

These connectors are often confused with
1/4-32
connectors; they look similar, varying only slightly
in size.
If in doubt,
check your mating connector using a thread gauge or
caliper: 1/4-32 threads have a
minor diameter
of approximately 5.4 mm, while 10-32
threads have a minor diameter of about 3.9 mm. See a
thread chart
for more details.

About Low Noise Cable

This is a "low noise" cable, with a carbon-impregnated conductive
PTFE
layer added around the
PTFE
dielectric; this layer helps to increase shielding, dissipate static
charge, and reduce mechanically-generated electrical noise as the
cable is flexed. This extra protection is useful for long cable runs,
low-voltage signals, high-vibration environments, in applications
including aerospace, automotive, NDT, strain gauges and
accelerometers, and extremely high fidelity professional audio
production.

Low noise cable is generally not recommended for RF use. In our own
testing, we see characteristics which differ from ordinary cable,
including phase delay and impedance variations with frequency. In the
field, we've seen mixed results in the GHz range; low noise cables
seem to provide the best results at signal frequencies in the low MHz
or lower. Ultrasonic NDT, for example, uses low-noise cable with
signals as high as 100 MHz, but in transient pulse trains, where phase
delay is less critical. The results you get will depend on the
application, and as always you will want to do your own testing before
ordering large quantities.

We hi-pot test our cable assemblies for high-voltage breakdown
between core and braid. See About Hi-Pot
Testing for why this might matter to you, particularly for
physics or NDT applications. Caution: We make no claims as to the
safety of this product for high-voltage use. These voltages can
kill. Do not handle or approach any cable or conductor carrying
high voltage; this includes insulated cables, nearby metal parts,
water, and other conductive materials. Engineering and design for
safety in your application are your responsibility.

Customization and Ordering

We make our own cable assemblies. If you need a connector
type that you don't see here, or if you have custom requirements,
feel free to contact us.
